目的：双源双能量低剂量CT在诊断儿童泌尿系结石中的应用价值。方法该研究将探究采用双能量CT技术在新疆南疆地区儿童输尿管结石疾病诊断和鉴别诊断的意义,然后比较其图像质量、信噪比、病变检出率这几方面,分析其在临床诊断中的可行性,将56例儿童病例分CT检查组及超声检查组,分析两组间对于难诊断型输尿管结石的统计学差异。结果双源双能量CT诊断输尿管结石儿童56例,所有病例均经过B超检查,其中1例腹段、3例盆段、2例多发输尿管结石B超未诊出或漏诊；CT诊断47例有肾积水、其中14例伴有中重度积水,9例有合并泌尿系的感染,2例诊断为泌尿系结核,1例为神经源性膀胱。结论双能量低剂量CT诊断常规检查方法没有诊出,对并发症、合并症的发现有很好诊断价值。

Objective To explore the application value of low-dose dual-source dual-energy CT in the diagnosis of urinary tract stones in children. Methods This study will explore the dual energy CT technology in southern xinjiang xinjiang regional chil-dren's disease diagnosis and differential diagnosis of ureteral calculi application value, and the image quality, the signal-to-noise ratio, lesion detection rate and identify differences, evaluate the feasibility of its application in clinical, 56 children cases CT in-spection and ultrasonic inspection group, analysis between the two groups statistically for difficult diagnosis of ureteral calculi. Results The dual source CT dual energy diagnosis of 56 cases of ureteral calculi children, all cases by ultrasound, including 1 case of abdominal segment, 3 cases of basin section, 2 cases of multiple ultrasound was not diagnosed or missed diagnosis of ureteral calculi. CT in the diagnosis of 47 cases with kidney seeper, 14 patients with moderately severe water, 9 cases with merger of urinary tract infection, 2 cases of diagnosis of urinary tuberculosis, 1 case of neurogenic bladder. Conclusion Low-dose CT in the diagnosis of dual energy not diagnosed with routine inspection method and its complications, complications were found very good diagnostic value.
